Sweep2 tangency option

When doing Sweep2 and you select tangency, i.e. tangency is given as an option to choose, sometimes the resulting surface is not able to join and later results in naked edge.

The surface is not even connected, so it seems strange the tangency option is selectable.
or is it close to tangent and do match command later?

@Toshiaki_Takano, did you see that with the “Do not simplify” option enabled ?

It would be easier if you can post an example file.

I’ll check my settings.
Thanks.
Probably written this on smartphone on the go, but should have followed up and posted something. Thanks again.
